AvamarDeduplication Backup Software and System

Overview:

EMC Avamar enables fast, efficient backup and recovery through its integrated variable-length deduplication technology. Avamar is optimized for fast, daily full backups for virtual environments, network-attached storage (NAS) servers, enterprise applications (Microsoft, IBM, Oracle, SAP), remote offices and desktops/laptops. By deduplicating data - identifying only unique daily changes - Avamar reduces backup storage and network bandwidth consumption by up to 95%. All data is always encrypted and compressed in-flight to meet security and compliance regulations. And with EMC CloudBoost, you can use Avamar to deliver long-term retention of backups in the leading private or public cloud of your choice.

Avamar is available standalone or as a component of EMC Data Protection Suite, which offers you a complete suite of data protection software options.

Companies are redefining their backup and recovery solutions to meet the needs of
exponential data growth, regulatory compliance, increased service-level agreements,
and shrinking backup windows. IT faces additional challenges brought on by
accelerated virtualization, converged infrastructure and the need to improve data
protection across the enterprise, including remote offices and cloud.

EMC® Avamar® software and system provides flexible deployment options for fast, daily
full backups and is part of the Data Protection Suite Family.

Management is simple through a centralized web-based management and at-a-glance
dashboard view, allowing you to protect hundreds of offices worldwide from a single
console.

Never Backup the Same Data Twice

Avamar divides backup data into variable-length sub-file segments, compresses and
applies a unique hash identifier to each segment during the backup process. Avamar
then determines if a segment has been previously backed up and only backs up the
unique segments. Avamar will never backup the same data twice.

Highly Efficient Data Deduplication

Avamar employs the most efficient client-side deduplication on the market. Variablelength
deduplication significantly reduces backup time by only storing unique
segments while maintaining daily full backups for immediate, single-step image
restore. Deduplication dramatically reduces the amount of data sent and stored -
eliminating backup bottlenecks and reducing storage costs.

Variable-length deduplication is a key feature in eliminating redundant data at a subfile
level. This method of deduplication is more efficient that traditional fixed-length deduplication. With deduplication using fixed-length segments, even small changes to a dataset will trigger a backup of the entire file.

Recoverability

You can take advantage of a one-step recovery from image level backups. Instant
access to VMs backed up to Data Domain further simplifies and optimizes the recovery
of your VMs. With instant access, the VM is mounted on a Data Domain and vMotion
orchestrates the recovery back to production storage. In addition, application
consistency ensures you can protect your applications with no downtime.

Scalability and Reliability

When deploying Avamar with Data Domain as the backup target, you will reduce the
costs involved with backing up and replicating data for disaster recovery. Data
Domain Replicator software provides automated, policy-based, network-efficient, and
encrypted replication for disaster recovery and multi-site data protection.

EMC Avamar Data Store combines EMC certified hardware and Avamar deduplication
backup and recovery software in a fully integrated, scalable, pre-packaged solution. In
addition, it eliminates single points of failure by employing patented redundant array
of independent nodes (RAIN) technology to provide high availability across nodes in
the Data Store. System and data integrity are verified daily to ensure recoverability.

VMware
Avamar takes advantage of VMware Changed Block Tracking (CBT) for both faster
backups and restores. For image backup, Avamar maximizes throughput by using
intelligent load balancing across multiple proxy VMs. Avamar provides fast, singlestep
recovery of individual files or complete VM images to the original VM, an
alternate VM or a new VM. For VM images stored on a Data Domain Systems, a VM
can be instantly accessed, and while running be vMotioned back to the production
environment.

Avamar has tight integration into VMware and enables self-service data protection.
vAdmins run backups and recoveries without ever leaving vSphere. Avamar
integration with vRealize Automation (vRA) and vCloud Director (vCD) provide data
protection services for public cloud, private cloud, hybrid cloud and born-in-the-cloud.
The vRA Data Protection Extension embeds data protection directly into the blueprints.
These blueprints ensure that data protection is always applied during the VM
provisioning process. In addition, vAdmins manage data protection from within the
vRA UI. The vCD Data Protection Extension embeds backup services right into vCloud
Director and can be shared and distributed in a multi-tenant model.

Microsoft
Avamar provides fast, efficient data protection of your Microsoft private and hosted
clouds, including Hyper-V and Azure. It is simple to protect your mission critical
applications by leveraging the interfaces that you already use when managing your
applications. Application admins are empowered to centrally manage the data
protection of their Microsoft applications. Backup administrators are responsible for
assigning the appropriate data protection policies using Microsoft System Center
Virtual Machine Manager. Policies are enforced when the virtual machines are
provisioned.

Avamar will protect each VM via an image based backup method. By understanding
the virtual hard disk format, the backup application will scan the VM files directly in
the Hyper-V file system, processing the data more efficiently than an agent-based
method. Cluster Shared Volumes (CSV) allows multiple nodes to have access to all
disks within the clusters. With Avamar, you can designate multiple proxy node
systems for your backup. This brings performance benefits by allowing any host
within the cluster to perform a backup.

Highly Efficient Backup of NAS and High Density File Systems

Avamar provides fast, reliable NAS system backup and recovery via the Avamar NDMP
Accelerator node. With this approach, a level-0 backup is performed only once, during
the initial full backup. Subsequent daily full backups are achieved by requesting only
level-1 incremental dumps, and building them into a daily full backup view. This
dramatically reduces backup times and the impact on NAS resources, and allows an
easier and faster recovery. Avamar eliminates backup bottlenecks and provides the
freedom to consolidate storage and optimize NAS systems—without limiting the
number and size of files or volumes—to meet the backup window. With automated
multi-streaming, Avamar can protect large scale-out NAS systems, including EMC
Isilon, by delivering increased throughput to protection storage.

Avamar’s Fast Incremental architecture provides an efficient solution to protect highdensity
file systems (HDFS). The traditional file-based backup approach for protecting
HDFS cause bottlenecks by scanning/reading the entire file system during a backup.
Linux Fast Incremental is aware of changes made to a file system, eliminating the
need to perform a file-scan during the backup and eliminating the bottlenecks of
traditional file-based backups.

Fast Desktop/Laptop Backup

Avamar delivers efficient data protection for desktop/laptop by providing data
deduplication, open-file backup, and CPU throttling. Avamar leverages existing
network links, and since it operates in the background, it is not disruptive to endusers.
Data is automatically backed up when a user is attached to the network during
normal backup windows. Avamar enables self-service backup and recovery. End
users can initiate an on-demand backup and quickly recover their own data anywhere,
anytime, via an intuitive interface and integrated search engine. The recovery is
always just one-step.

Extended Retention

Avamar helps companies meet compliance regulations that require extended
retention of data by sending backup data to a media access node, which then places
the data on a VTL or tape. Data is stored in the original format maintaining all
permissions and attributes, which supports offsite restores for eDiscovery.

Centralized Management and Contol

Backup and Recovery Manager provides control and monitoring for Avamar,
NetWorker and Data Domain systems from your tablet. It requires no license and is
installed by any customer leveraging the Data Protection Suite Family.

Flexible Deployment Options

Software-only deployment
EMC Avamar Virtual Edition (AVE) is the industry’s first deduplication virtual
appliance for backup and recovery—consisting of customer installable EMC Avamar
software deployed as a virtual appliance. AVE enables the deployment of a
complete Avamar server on an existing VMware ESX server or Microsoft Hyper-V
server. The AVE can scale up to 16 TB when configured with Data Domain Virtual
Edition as the storage system. Since all aspects of the backup and recovery process
are encapsulated and virtualized, control and management are streamlined,
reducing demands on your IT staff.

Remote Office
Avamar lightweight software agents can be deployed on servers with no additional
remote hardware required. This enables data within a remote office to be backed up
directly over an existing WAN link to a Data Domain system or Avamar Data Store
residing within the data center, eliminating the need for local tape backups and offsite
tape shipment risks.
